Two algae cells

Two algal cess shaped like slendar half moons are touching at one end. We can see small particles moving in on of the algae. A Euglena stops by for a short visit, then goes on its way.


Commentary by Prof. Yuji Tsukii, Hosei University
This organism looks similar to Cymbella, but its shape would seem to indicate Amphora.
